Over the years knowledge was a desire of many people for its eternal value. Knowledge is essential to the continued success and progress of human life, considered to be one of the most precious and infinite resources that life can give to someone. One place to look for clues about how knowledge affects our lives is our past. History is written entirely by what is attributed to Winston Churchill. However, thanks to such recording methods, the stories of victory are biased, their views on the past are biased, sometimes even not even known to them when the generation died.
The word "science" comes from the word "science" in Latin and represents "knowledge". Today, the definition becomes more complicated, mainly involves a gradual process of knowledge acquisition. In the dictionary, science is defined as "a knowledge system covering general truth or general law operation, especially by scientific method" (Merriam-Webster 2011). One of the main goals is to discover the persistent principle of the world of phenomena. Natural phenomena of natural science such as mathematics and physics, social science research, human behavior, organization and society. An important paradigm in science is the knowledge and results gained through a series of different steps based on the so-called "scientific method" and observable phenomena that can be verified by other researchers in a similar environment It is an empirical method that you need. Popper 1959)
Knowledge acquisition can be divided into several stages in several ways. To get a deeper understanding of knowledge acquisition, two different methods were compared. The comparison method is the Knowledge Acquisition DS method and framework proposed by George Klinker and gave classification of existing tools. They are not considered for installation, use or retirement as they are not interested here. For each stage, Clinker explains the existence of tools and research on that subject. Several terms are used in both ways, but because of their different meanings, some terms are contradictory. For example, the term "life cycle" refers to a series of phases in which Klinker resides in the knowledge base, but when used in Knowledge Acquisition DS it refers to aspects of project management. There is some contradiction in using the word "task".
